Double pressure measuring instruments contain two separate measuring systems that are independent of one another which in one instrument display , for example , the brake pipe pressure and the reservoir pressure 应用于轨道机车和卡车的气压制动器设备上的压力测量技术拥有双值的压力测量仪表，一个仪器中包含两个独立的测量系统。例如，制动管压力和蓄水池压力。
The inertia power was analyzed during the freightage in the article , and according to the results ; the rope lug was designed , the roof wooden structure was optimized . especially aiming at some problems of the quality of the sample surface and the reliability of the door lock ; some effective measures were introduced ; the brake system was changed with stainless steel pipes , and the fitting location of the brake setting was adjusted 文中详细分析了货物在运输过程中产生的惯性力，以此为依据设计了固定货物的绳栓；优化了车顶木结构、针对样车在外观质量和门锁可靠性方面存在的问题，提出了对应的改进措施，并改用了不锈钢制动管系，调整了空气制动装置的安装位置。
